Episode Details

Microsoft Copilot top prompts: in this episode of M365.fm, Mirko Peters stops talking about prompting theory and shows his actual, battle-tested prompts that he uses every day across Microsoft 365—the ones that cut meeting prep from thirty minutes to five, turn email threads into structured decisions, and make weekly reports write themselves. No filler, no vague advice: just prompts that work, with the context behind why they work.

Mirko starts by explaining what separates a useful prompt from a mediocre one in his daily practice. The key is specificity about role, output format, and constraints—not length. He shows how "summarize this" produces generic noise, while "act as a project manager, extract the three open decisions from this thread, list them as bullet points with the owner and due date" produces something you can actually send to your team. The difference is not prompt length; it is structural clarity.

He then walks through his top prompts category by category. In Outlook, he uses Copilot to triage long email chains, draft responses that match the sender's tone, and pre-write follow-ups based on conversation history. In Teams, he extracts action items mid-meeting, generates a decision log before the call ends, and creates a one-paragraph executive summary that goes straight into the meeting notes. In Word and PowerPoint, he builds first drafts from a bullet-point outline and refines them with targeted editing prompts rather than regenerating the whole document.

The episode also covers context injection—the technique of pasting your own templates, past examples, or company vocabulary directly into the prompt so Copilot imitates your actual style instead of producing generic corporate output. Mirko shares prompts for strategy documents, status reports, and leadership updates that use this technique to produce outputs he barely needs to edit, because the AI already knows the structure, the tone, and the audience.

Throughout, he emphasizes iteration over perfection. None of these prompts were written perfectly the first time; they were refined through dozens of tries, small adjustments, and learning what Copilot does well versus what it consistently gets wrong. The real takeaway is not the prompts themselves but the habit of treating Copilot as a collaborator you coach rather than a machine you command with a magic phrase.

WHAT YOU WILL LEARN

• What makes a Copilot prompt specific and structural enough to produce usable output.
• - Top prompts for Outlook: triage, tone-matched replies, and follow-up drafts.
• - Top prompts for Teams: action items, decision logs, and executive summaries mid-meeting.
• - How to use context injection to make Copilot match your templates and brand voice.
• - Why iterating prompts over time beats searching for a single "perfect" prompt.

THE CORE INSIGHT

The best Copilot prompts are not clever—they are specific. Once you stop asking Copilot to "help" and start giving it a role, a format, and a constraint, you stop getting generic summaries and start getting outputs you can actually use without rewriting them from scratch.

WHO THIS EPISODE IS FOR

This episode is ideal for Microsoft 365 Copilot users who already have access but feel like they are not getting the value they expected. It is especially useful if you are still using generic prompts, getting inconsistent results, or spending as much time editing AI output as you would have writing it yourself.
